Japanese Scientists Regenerate Human Hair on Bald Mouse, Tokyo University of Science Study

Scientists in Japan may have good news for those going thin on top. A team at Tokyo University of Science has successfully regenerated hair on a bald mouse in a breakthrough that might eventually generate an alternative to hair transplants for those looking beyond comb-overs and toupees to cover their exposed pates. After cultivating two different kinds of cells taken from hair follicles in mice, the team transplanted the cells into the hair follicles of a bald mouse. Within three weeks, 74% of the hair follicles implanted with the cells grew back hair. The new hair connected with nerves and surrounding tissues showing that the follicles had become fully functional and were able to regrow hair even after hair was pulled out.
